Good idea.

Agreed.

The old gdmd did parse dmd.conf, but arguably it should be parsing
gdmd.conf instead. I suppose the idea is that gdmd should be a drop-in
replacement for dmd, so if no gdmd.conf is found, it should probably
fall back to parsing dmd.conf? Not sure what to do with the conflicting
libraries problem, though.
